To withdraw 50.0 MLD sewage from the existing outfall sewer in the area to reduce the load on the existing outfall.

To treat the collected waste water and the sewage withdrawn from the outfall to the standard laid down parameters ensuring no nuisance during treatment in the area.

To deliver the treated effluent to suitable points within the proposed lined section of the drain from Ch 5.1 km to Ch 34.8 km in a manner to ensure continued water flow in the entire bed width within the drain section of sufficient depth as stipulated and of quality appropriate to meet the class D of CPHEEO standards for streams suitable for aquaculture.3 OUTLINE of presentation

TRIBUTARY DRAIN 2

1 AMANISHA NALLAH5 AMANISHAH nallah Amanishah Nallah is the MAJOR DRAIN OF JAIPUR CITY. This Nallah travels a distance of about 47.5 KMs FROM THE ORIGIN POINT TO CONFLUENCE POINT OF DHUND RIVER

Dravyawati river is the new name given to Amanishah Nallah which originates from the hills of Nahargarh fort and TRAVELS THROUGH THE CITY OF JAIPUR THROUGH THICKLY POPULATED RESIDENTIAL COLONIES.

Entire length of Nallah has been DIVIDED INTO DIFFERENT REACHES for convenience

DIFFERENCE IN ELEVATION from zero chainage to chainage 47.5 km is 134 m

The Nallah CARRIES STORM WATER DURING MONSOON SEASON. In additions to

storm water drains, LARGE NO OF UNTREATED SEWAGE CARRYING DRAINS ALSO JOINS THE NALLAH AT VARIOUS LOCATIONS.6 TRIBUTARY drains & RAIN WATER streams Clause 5.2.2 : About 12 big drains joins the Nallah and 75 nos untreated sewage carrying drains joins the Nallah at various locations

Clause 5.2.4 : The list of the observed locations where such waste water finds entry in the drain have been given in Annexure 10 of the contract document. TOTAL NO OF TRIBUTARY DRAINS are 81 nos TOTAL FLOW is appx 152.937 MLD

Clause 5.2.15 : At some places there are FEW EXISTING RAIN WATER STREAMS, WHICH ARE NOT CONNECTED TO NALLAH.

Clause 5.2.4 : The major portion of the dry weather flow collected flow under the B2 by pass where it was measured as about 100 MLD7 SEWERAGE network Clause 5.2.4 : IDEALLY THERE SHOULD BE NO DRY WEATHER FLOW IN THE DRAINS ENTERING THE AMANISHAH DRAIN and the waste water should be collected through sewerage system and connected to a STP.

Clause 5.2.4 : There are areas which have been sewered and are TRANSFERRING UNTREATED SEWAGE INTO THE TRIBUTARY DRAINS.

Clause 5.2.4 : Major part of the catchment has been sewered but still some areas need to be sewered and new areas will also develop. Providing of the SEWERAGE SYSTEM IN THE CATCHMENT AREA IS NOT A PART OF THIS CONTRACT.8 PROPOSAL as per contract

OUTLETS OF SEWERAGE SYSTEM WILL BE DISCONNECTED FROM TRIBUTARY

DRAINS and connected directly to Intercepting pipes. Therefor, reduced flows will be considered for design of section for tributary drain.

Clause 5.2.4 : Areas where SEWERAGE SYSTEM DOES NOT EXISTS with in a distance of 500 m EXPECTED DRY WEATHER FLOWS IN THE DRAINS HAS TO BE ESTIMATED FOR NEXT 30 YEARS and the section of drain to be provided accordingly.

INTERCEPTING CHAMBERS will be provided at the ENTRY POINT OF TRIBUTARY

SECTION X-X WEIR WALL TRIBUTARY DRAIN Y FLAP X VALVE SECTION Y-Y11 INTERCEPTING chambers / storm water OUTFALL Clause 5.2.4 : It will be ensured that FLOW IN THE AMANISHAH DRAIN at that point DOES NOT FLOW BACK INTO THE INLET Well try to keep I.L. of Storm Water Pipe above HFL of Amanisha Nallah as possible and a Flap valve will be provided near the outlets for preventing reverse flow. Clause 5.2.4 : ARRANGEMENTS FOR CLEANING THE TRAPPED FLOATING MATERIAL will be provided. AMANISHAH NALLAH INTERCEPTING PIPES Y X SCREEN

DPR : There are 82 SUCH LOCATIONS. It is required to extend the colony

sewerage network over an average distance of 500 mtrs (using 250 mm RCC NP3 Hume Pipe) upto the Nallah so that the sewage can be channelized to intercepting pipelines.

Lifting stations, if required, will be provided to lift the sewerage from colony sewerage networks to intercepting pipes.

Double Wall Corrugated HDPE Pipes proposed as per IS 16098 (part 2).

DWC Pipes are ABRASION RESISTANT, LIGHT IN WEIGHT but very STRONG, less leakage and infiltration, Low Operational Cost, FLEXIBLE (and hence less brittle), and have more ECOLOGICAL FOOTPRINT.13 ADVANTAGES OF DWC PIPE

RIGID RCC PIPE FLEXIBLE DWC PIPE

14 INTERCEPTING PIPES Clause 5.2.4 : DRY WEATHER FLOW FROM ICs AND SEWERAGE LINES FROM COLONY SEWERAGE NETWORKS, wherever provided, will be tapped and CONNECTED TO A INTERCEPTING PIPES proposed to run along the alignment of the Amanishah Drain on both the banks. This shall flow towards the downstream until it is picked up as the tapping point of sewage treatment plants proposed in this contract. There are approx. 11 proposed Sewage Treatment Plants on the left and right bank of Nallah. Lifting stations are provided on either one bank or both banks depending on the sewage flow source i.e., incoming drain channels to the interceptor pipelines. Clause 5.2.4 (A) : INTERCEPTING PIPES WILL BE PROVIDED WITH MANHOLES, VENT PIPES, VALVES ETC as per the sewerage/storm water flow norms and will be laid in gradient so as to maintain gravity flow. Lifting stations, if required, will be provided along the intercepting pipes at places other than those meant for STPs.15 RAIN WATER streams Clause 5.2.15 : At some places few EXISTING RAIN WATER STREAMS are not connected to Nallah, which are now TO BE DIVERTED TOWARDS NALLAH. Necessary civil works required for bringing additional rain water streams in to the Amanishah Nallah are to be done.

Clause 5.4.6 : All existing Kutcha rain water Nallah within a vicinity of 500 m from the main Nallah are to be diverted to main Nallah and shall to be LINED IN LENGTH OF 500 M AND A SCREEN IS TO BE PROVIDED AT THE ENTRY POINT.16 SUBMISSIONS & DATA REQUIREMENTS DESIGN BASIS REPORT TRIBUTARY DRAINS

25 WHY WE ARE DIFFERENT ! In most engineering-intensive organizations, a majority of the DESIGN ENGINEER'S TIME IS SPENT ON ROUTINE, REPETITIVE TASKS THEREBY LIMITING HIS/HER TIME AND MINDSPACE FOR CREATIVITY AND INNOVATION.

We IDENTIFY REPETITIVE TASKS, achieve consensus on the best practices to

accomplish each task and AUTOMATE IT TO A USER-FRIENDLY LEVEL.

It has often been said that A PERSON UNDERSTANDING OF A CONCEPT

IMPROVES WHEN HE TEACHES IT TO SOMEONE ELSE.

We believe that a person understanding of concept is complete when he teaches

it to a computer, i.e., express it as an algorithm THE ATTEMPT TO FORMALIZE THINGS AS ALGORITHMS LEADS TO A MUCH DEEPER UNDERSTANDING than if we simply try to understand things in the traditional way.

OUR USP GIVING TECHNICALLY CORRECT, ECONOMICAL & PRESENTABLE

OUTPUTS IN RECORD TIME TO THE SATISFACTION OF THE CLIENT.26 AUTOMATION IN WORKING USE OF STANDARD AND REPUTED SOFTWARES ETABS, SAP2000, SEWERGEMS, WATERGEMS

Developing in-house software WE HAVE COMPLETE COMMAND OVER THE USE

OF PROGRAMMING LANGUAGE for EXCEL, called VBA and programming language for AUTOCAD, called AUTOLISP and FORTRAN.

Using high-end programming we have been able to make EXCEL AND AUTOCAD TALK TO EACH OTHER in many of our processes. This STANDARIZES THE PROCESSES and so the OUTPUT BECOMES COMPANY SPECIFIC RATHER THAN PERSON SPECIFIC.27 ECONOMY IN DESIGN Achieving ECONOMY in safe design is the ENDEVOUR OF EVERY CONSULTANT.

We keep very CLOSE WATCH ON THE STATS RELATED TO ECONOMY. Excel sheets give the ESTIMATED QUANTITIES ALONG WITH THE DESIGN ON THE FLY. Therefore, design engineers remain conscious of this aspect.

We can provide rough estimated quantities even before the drawings are ready. This is possible because ESTIMATE FOR MOST OF THE COMPONENTS GET GENERATED DIRECTLY FROM PRELIMINARY DESIGN.

Complete INTEGRATION OF PROCESS OF DESIGN, DRAWING & ESTIMATION saves

precious time and allows for WORKING ON VARIOUS OPTIONS AT PLANNING STAGE.28 sample automation in NETWORKS
